Level 1 sweep and inspection to the NFPA 211 annual standard - flue, crown, cap, and flashing checked and photographed
Chimney sweep logs do not sweep chimneys. They loosen some creosote - which then falls where a brush and vacuum still have to collect it.

Why Top Hat Chimney Is New Hyde Park’s Preferred Chimney Cap & Crown Company
Ask anyone on your street. We’ve been inside more New Hyde Park chimneys than we can count, and we know exactly what the post-war houses here throw at you. The Capes off Marcus Avenue, the split-levels near Denton Avenue, the Colonials around Herricks Road, they were all built the same way between 1945 and 1965, and they all age the same way. That matters when you’re deciding whether a crown needs coating or full replacement.
Every job gets the same treatment: upfront pricing before a single tool comes off the truck, and a 90-Day Done Right Promise in writing. If it’s not right, one call brings Wendell back. His license number is published, his address is published, and he runs into you again at the bagel shop on Saturday. That’s the difference between a local sweep and a franchise that rotated in last spring. New Hyde Park homeowners call us because the person who answers the phone at 2 a.m. may well be the same person who shows up at your door.
Our Chimney Cap & Crown Services in New Hyde Park
Cap Installation
A properly sized cap does two jobs in New Hyde Park: it keeps nor’easter rain out, and it stops downdrafts that push smoke back into your living room on windy nights. We install stainless and copper caps sized to the actual flue diameter, not whatever was on sale at the big-box store. For the fuel-converted oil-to-gas chimneys common in this hamlet, that sizing matters more than most homeowners realize. We’ll show you why with a camera before we quote.

Cap Replacement
Rusted Famco caps are everywhere in New Hyde Park, especially on houses built in the 1950s and 1960s where the original cap predates the gas conversion. When the cap legs pull loose from a spalling crown, water gets in and the cycle accelerates. We replace with Olympia Chimney caps or equivalent, anchored into sound masonry, not screwed into crumbling mortar. You’ll see the old cap and the new one side by side before we leave.

Crown Repair
The crown is the concrete slab at the top of the chimney, and on 60-to-80-year-old New Hyde Park brick it’s usually cracked, spalled, or pitched wrong. We grind back the loose material, rebuild the wash edge with proper overhang, and seal it. The goal is simple: water runs off the crown instead of soaking into the brick below. On most converted gas flues, crown failure is the first domino that leads to liner replacement. We’d rather catch it at the crown.

Crown Coating
When the crown is still structurally sound but the surface is porous, a coating like Gelco CrownSeal buys years of life for a fraction of replacement cost. We apply it only after the crown is clean and dry, and only when the masonry below is sound enough to justify it. If the crown is too far gone, we’ll tell you plainly and show you the camera footage. We never sell a coating on a crown that needs a rebuild. That’s the whole point of our Chimney Cap & Crown work: fix what’s fixable, replace what isn’t, and always show the homeowner why.

Common Chimney Cap & Crown Problems We See in New Hyde Park Homes
- Freeze-thaw spalling at the crown edge. The original 1950s mortar joints in New Hyde Park brick chimneys are softer than modern mixes. Winter freeze-thaw cycles pop the crown’s outer edge, water seeps into the smoke chamber, and the anchor ring for your cap loses its grip. We see this weekly on Capes and split-levels across the hamlet.
- Third-degree creosote glaze from 1980s wood inserts. Homeowners who had wood-burning inserts installed during the oil-crisis years rarely relined the flue. The restricted airflow bakes creosote into a hard glaze, and that heat stress cracks the top course of the clay tile liner, which transmits to the crown above it. Nassau County code now requires a full UL-listed liner before any such insert passes inspection.
- Nor’easter negative draft pulling rain past a deteriorated crown-to-flue joint. The rapid pressure drops in coastal Nassau County create strong negative draft events. On an oversized gas flue, that pulls rain through a failing joint, condensing inside the flue and leaching efflorescence through the brick below the cap. It shows up as white staining on the chimney face facing the prevailing wind.
- Rusted cap legs on fuel-converted chimneys. The original oil-boiler flue was sized for high-BTU combustion. After conversion to gas, the flue runs cool and wet. Condensation drips onto the cap’s anchor ring, rusts the legs, and the cap pulls away in the next strong wind. We replace these constantly on homes off Jericho Turnpike and throughout the Lakeville Road corridor.

FAQs - Chimney Cap & Crown in New Hyde Park
Yes, in most cases. The crown on a 60-to-80-year-old New Hyde Park chimney is already compromised by decades of freeze-thaw cycling, and occasional burning doesn’t protect it from nor’easter rain or the condensation created by your converted gas flue. A Gelco CrownSeal coating is cheap insurance, usually $200-$300 as part of a crown repair job, and it arrests the deterioration before you need a full rebuild. Call (516) 963-1068 and we’ll give you a straight answer after looking at it.
It can, and that’s exactly what we see throughout New Hyde Park. When a chimney built for an oil burner vents a modern gas appliance, the flue runs cooler and wetter. That condensation drips onto the cap’s base and legs, accelerating rust. The fix is a properly sized cap, sometimes paired with a liner adjustment, and we’ll show you the sizing math on camera before we touch anything. We never install a cap on an oversized flue without pointing out the condensation issue first.
Usually yes, but the liner question has to be resolved first. Most 1980s inserts in New Hyde Park were installed into oil-boiler flues without relining, and Nassau County code now requires a UL-listed liner. If the liner is sound and the crown is repairable, we’ll install a correctly sized cap and coat the crown. If the liner is cracked or glazed, we’ll show you the footage and quote the liner as a separate line item. You decide after you’ve seen what we see. Call (516) 963-1068 for a free camera inspection.
The crown is the concrete slab that caps the masonry; the chimney cap is the metal hood that covers the flue opening. On converted gas flues in New Hyde Park, the crown usually fails first, because it was poured in the 1950s or 1960s with a soft mortar mix and has been absorbing rain and freeze-thaw damage for six or seven decades. The cap then rusts out because it’s anchored into that failing crown. That’s why we always evaluate both as a system, not as two separate line items.
That’s the cleanest solution, and it’s what we recommend on most two-flue Cape Cods here. A single multi-flue cap covers both openings, simplifies the anchor points, and looks cleaner from the street. It also eliminates the gap between two separate caps where water and debris collect. Expect to pay $500-$900 for a properly sized stainless multi-flue cap in New Hyde Park. Call (516) 963-1068 and we’ll measure both flues and give you a flat number before you commit.
One Thing New Hyde Park Homeowners Should Know About Their Chimneys
New Hyde Park’s dense grid of post-WWII Cape Cods and Colonial Revivals, built rapidly between 1945 and 1965 during Long Island’s suburban boom, were originally heated by oil burners venting through masonry chimneys sized for high-BTU oil combustion. When those homes converted to natural gas decades later, the flues stayed the same size. Now they’re two to three times larger than needed. The result is cold-drafting and condensation inside the flue, which accelerates clay-tile liner deterioration and directly undermines the crown and cap above. This is not a theoretical problem. It’s the single most common failure pattern we see in the hamlet, and it’s why we never recommend a cap or crown repair without camera footage you can watch over our shoulder. If we’re not willing to show you the inside of your flue, we don’t deserve the job.
Our crew capped a 1958 Colonial on Jericho Turnpike where a rusted Famco cap had pulled away from the spalling crown, letting nor’easter rain erode the clay-tile flue top. We ground back the crumbling crown, coated it with Gelco CrownSeal, and set a properly sized Olympia Chimney cap over the converted gas flue. Then we ran a camera to show the homeowner the hairline cracks we’d sealed before they became a reline job. That’s the standard on every single job: the camera footage and a plain-English verdict, every time, no exceptions.
